Abstract
Relevance and materials. The soil humidity being a major factor of its fertility can meaningfully change at the earth surface. R esults of researches of dependence of soil reflectance spectrum from soil type and its wetness parameters are described proanalytic conditions achievements high values of the signal reflected from wet soil are analyzed in relation to a series of measurements on multiple fields with different values of the Fresnel reflection.
Results. It is shown that taking into account the possible change in the mutual dynamics of changes in fw and d from in phase to ant phase, the averaged reflected signal reaches a minimum when the specified parameters are in-phase mutually changed. On the basis of the discovered fact, a heuristic recommendation was given to use that area of the volumetric water content in the soil, where the ant phase change of the indicated indicators is provided.
